Mountain of Youth Dynasty - or - The Cabin Fever Conundrum
This is based around Snowy Escape and a generational pilgrimage to the top of Mt Komorebi. Every heir must be conceived on Mt Komorebi Peak -- they don't have to be the firstborn, if your have more than one kid. Every generation, the heir must spend a cumulative 2 weeks on the peak of the mountain. There's a 20x20 lot, nice views, and you're going to get *very* familiar with it. At the end of that time, a sim who has completed a career can prepare ambrosia on the mountain peak and hence forth remain at this age. So, if they achieve this as a YA, then they -- or their spouse -- can remain as a YA forever.
⦁ You start your dynasty with 1 YA.
⦁ Once a sim is an "immortal", they can be split off into a new household that will be for immortals. It's unreasonable to expect a player to be interested in the same sims forever, or to end up managing 8 sims on a 20x20 lot. When Gen 1 is immortal, move them into a separate Immortal Household. And later on, when gen 2 is immortal, move gen 2 into that household. If we don't have the previous immortals around, it frees up space for family.
⦁ You can move non-heirs out.
⦁ Either play with aging off for non-active households, or use a Realm of Magic potion of immortality that stops aging, but this will require a mod. The goal is the same, to allow the player to move the immortal sims out and for them to not age and die. So yes, the ambrosia part is mostly ceremonial.
⦁ The dynasty is complete when your 8th gen immortal leads a mountain climbing expedition with the first immortal.
⦁ Plot twist: any sim eligible to eat the ambrosia may choose to make their spouse immortal instead of themself. No, the spouse doesn't have to have done all the requirements. Not at all. If Nigel Pancakes is the heir, he has to complete a career. He has to stay on the mountain. But he can make Mila Munch immortal.
⦁ Only children conceived on the mountain, or during the climbing expedition, can be the heir, first born or not.
⦁ By the time your current gen ages to elder, you must have an heir. If you have no eligible heir conceived on the mountain -- because you want to spend time away from the mountain (and I can't blame you) -- you will immediately summon the tragic clown, and that randomly generated sim will be your heir. May the RNG be always in your favour. A Sad Unhappy Clown Heir, or SUCH, only needs to spend 3 days on the mountain to become an immortal.
⦁ You may not leave your child behind while you live on a mountain for 3 weeks. Wait until they're teens and have the skill to climb the mountain, or have them born on the mountain, or summon them to the top when your sim is there.
⦁ There's no requirement that a child or teen be an A student. They can live on the mountain. That's fine, but for every 2 school days a child or teen misses because they're on the mountain, you have to mount 1 angelfish. This will affect your ability to make ambrosia. However, if you don't mind fishing a lot and have enough angelfish, a sim can rack up some time on Mt Komorebi Peak towards their cumulative 2 weeks, and be an immortal YA.
How to build your mountain chalet / hut / magic castle / nuclear bunker
The lot value cap initially is 20k. A starter home on the peak the first time you reach it. The allowed lot value will increase through the generations and milestones. Otherwise we'd just place a 200k house down, and there'd be no progression.
After that first climb, your allowed lot value increases thus:
⦁ For every sim in the family tree in the simology panel who climbs to the peak without dying, the lot value cap increases by 5k simoleons. If uncle Steve -- who isn't an heir -- climbs the mountain, great you can build a slightly nicer house. Get a fireplace. Get a big tv. If he climbs the mountain again sometime, great, that's another 5k. Get a nicer bed. I like this, because there's a reason to have more kids if you like that.
⦁ For every sim in the family tree in the simology panel who attempts to climb the mountain but dies horribly, the lot value cap increases by 10k simoleons. So... an incentive to take under-prepared family members up the mountain? Marry Vlad, then... bring him adventuring. But you can't just bring him, let the sunlight kill him, and get a nicer house. No, you have to marry him first, and then see how you feel about your plan.
⦁ For every heir conceived on the mountain, add another 10k to your allowed lot value.
⦁ For every non-freelance career completed, add 20k. --So there's incentive to race through some careers, it'll improve your mountain bunker.
⦁ For every Top Notch toddler raised on the mountain by an immortal, add 50k.

The main problem with this is the rock climbing skill is so painfully slow to learn compared others. Did it get patched at any point? That said, ROM magic brooms / wellness teleportation etc are fast ways to get up the mountain without climbing skill.
I'm also not really sure how to handle splitting the household between the sims who climb the mountain and the sims left behind. Maybe a rule that everyone has to stay together?
